        摘要：With the development of the "new vaccine",i. e.,subunit and especially synthetic peptide vaccine, the need for a safe and efficacious immunoadjuvant has become paramount because of the weak immunogenicity of the pure antigens. In this paper we review the various approaches that are being explored for the development of a safe and efficacious immunological adjuvant aimed at specifically increasing both the humoral and cellular immune response to a desired vaccine antigen. Among these approaches,the polymer adjuvant is highlighted,which encompass those improving the presentation of the various antigen (by controlled release or altering the presentation states) as well as those stimulating the immune cells,i.e., macrophages, T and/or B cells. It is expected that the biodegradable polymer immunoadjuvant is the most promising one that would be clinically acceptable in the near future.

        摘要：Synthesis and application of the starch copolymer were described in this paper. The starch copolymer were prepared by various method for example: free radical initiator,anion initiator and other copolymerization method. The starch copolymer were applied for thicking agents, flocculant,floatation agent,absorbents for aqueous fluids, paper additivies, sizing agents et al.

        摘要：The recent progress in crystal - amorphous interphases in binary polymer blends has been reviewed. A lattice theory that describes the structure and composition of the crystal amorphous interphases in binary blends were presented. The evidence for existence of the interphase has been delineated.

        摘要：Permeabilities of poly [1-(trimethylsilyl) 1- propyne] (PTMSP) to gases is higher than those of any other nonporous synthetic polymers whether they are glassy or rubbery at ambient temperature. PTMSP is in the glassy polymer state. The high gas permeability of PMSP results primary from substantial gas solubility and diffusivity, which appears to be due to,in turn, to a large excess free volume in the unrelaxed (Iangmuir) domains of this glassy polymer. The biggest problem with PMSP is the deterioration of its high permeability with the passage of time or thermal histeresis. Now, a lot of efforts is being devoted to solving this problem by the addition of less volatile materials, fluorination, bromination, copolymerization with other monomer, or blend with other polymetrs.
